Cooling Principles
Trio supports controlling up to two cooling devices (foggers or cooling pads). The devices
can run separately or together.
The relative humidity directly affects the ability of birds to cool down, even when the
temperature is the same (heat loss decreases in higher humidity rate causing heat stress).
What is important to remember is that the cooling process adds moisture to the air;
therefore it needs to stop when the relative humidity is too high.
•
To enable limiting cooling according to the humidity, install a humidity sensor.
•
Invalid humidity sensor readings are not taken into consideration.
To avoid causing the animals undo heat stress during periods of high relative humidity, Trio
employs the following rules:
•
When the temperature reaches the Cooling Temperature in the Temperature
Curve, cooling begins and continues until the temperature falls below this point.
The Cooling Temperature must be higher than the Target Temperature.
•
If the humidity level rises above the To Humidity parameter (plus the Humidity
Band), cooling ceases.
•
Cooling only takes place between the start and finish times.
•
When the minimum OFF time = 0sec, and the temperature reached ON temp +
Ramping range the cooling device operates continuously.
•
While cycling, the minimum OFF time will never be less than 5 seconds.
•
Cooling runs in all ventilation modes.
•
To record the amount of water used during cooling: install, map, and define a
water meter (refer to the Installation Manual).
